Antonio Sanchez 543e34ab9d Re-implement move assignments. 
The original swap approach leads to potential undefined behavior (reading
uninitialized memory) and results in unnecessary copying of data for static
storage.

Here we pass down the move assignment to the underlying storage.  Static
storage does a one-way copy, dynamic storage does a swap.

Modified the tests to no longer read from the moved-from matrix/tensor,
since that can lead to UB. Added a test to ensure we do not access
uninitialized memory in a move.

Fixes: #2119

Antonio Sanchez 2468253c9a Define EIGEN_CPLUSPLUS and replace most __cplusplus checks. 
The macro `__cplusplus` is not defined correctly in MSVC unless building
with the the `/Zc:__cplusplus` flag. Instead, it defines `_MSVC_LANG` to the
specified c++ standard version number.

Here we introduce `EIGEN_CPLUSPLUS` which will contain the c++ version
number both for MSVC and otherwise.  This simplifies checks for supported
features.

Also replaced most instances of standard version checking via `__cplusplus`
with the existing `EIGEN_COMP_CXXVER` macro for better clarity.

Fixes: #2170

Adam Shapiro 2ac0b78739 Fixed sparse conservativeResize() when both num cols and rows decreased. 
The previous implementation caused a buffer overflow trying to calculate non-
zero counts for columns that no longer exist.

Gael Guennebaud 82f0ce2726 Get rid of EIGEN_TEST_FUNC, unit tests must now be declared with EIGEN_DECLARE_TEST(mytest) { /* code */ }. 
This provide several advantages:
- more flexibility in designing unit tests
- unit tests can be glued to speed up compilation
- unit tests are compiled with same predefined macros, which is a requirement for zapcc

Gael Guennebaud c86911ac73 bug #1384: fix evaluation of "sparse/scalar" that used the wrong evaluation path. 2017-01-30 13:38:24 +01:00
Gael Guennebaud 296d24be4d bug #1381: fix sparse.diagonal() used as a rvalue. 
The problem was that is "sparse" is not const, then sparse.diagonal() must have the
LValueBit flag meaning that sparse.diagonal().coeff(i) must returns a const reference,
const Scalar&. However, sparse::coeff() cannot returns a reference for a non-existing
zero coefficient. The trick is to return a reference to a local member of
evaluator<SparseMatrix>.
